"The driver and his beloved dog were severely entrapped in the wreckage. The driver had sustained fatal injuries and there was nothing more paramedics could do for him and he was declared deceased on the scene," said Garrith Jamieson. 

"The K9 “Rasor” was also severely entrapped in the wreckage and suffered major injuries. The Lenmed ECP Paramedic Ceron Meadows stabilised the dog on the scene before she rushed it through to the Kloof and Highway SPCA where a team was awaiting her arrival. Unfortunately a short while later the dog too passed away due to its injuries."
